Cheap PCB prototyping & manufacturing in China – reviews

Review of some Chinese PCB prototyping services and manufacturers

I’m in progress of testing some of cheap Chinese PCB manufacturers. I’m going to try to write detailed description for each of them.

Tested so far:

Smart Prototyping – PCB Prototyping review

ShenZen2U and SmartPrototyping looks bascily like the same company. But they are not (as SmartPrototyping explained).

SeeedStudio.com Fusion – New PCB Services from popular DIY and prototyping company

https://www.seeedstudio.com/fusion_pcb.html

I discovered SeeedStudio some time ago, since the company is pretty active in the internet (facebook, own wiki, some projects on github). Last month they introduced PCB manufacturing services, called „SeeedStudio Fusion Services”

I decided to give it a try, because the website looked pretty neat and modern. They also provided (see below) a little bit better specs than the others.

Dangerous Prototypes – PCB Manufacturer Review

http://dangerousprototypes.com/store – another brand of DirtyPCBs, probably their „beta” site

My orders

For now, I have places three orders there, all with the same specification:

  • PCBs:
    • FR4
    • 2 layers
    • 10cm x 10cm
    • 10 pcs
    • 1.6mm thick
    • 1oz/ft2 = 35um
    • HASL
    • Green
  • Stencil: frameless

In one of my orders I also used free „panelization”. They allow to duplicate the same layout over one board – I had 4x 4.5cm x 4.5cm over one 10cm x 10cm piece.
